DEVICE FOR WITHDRAWING LIQUID FROM METAL CONTAINERS Filed 001;. 8, 1936Patented Feb. 16, 1937 UNITED STATES PATENT OFFICE DEVICE FORWITHDRAWING LIQUID `FROBI METAL CONTAINERS 14 Claims.

My invention relates to a device for withdrawing liquid from containersand which provides in combinationy a container opening, venting, andvent filtering means for attachment to and use in connection with thecontainer from which the liquid is to be drawn.

One of the purposes of my invention is to provide means whereby a can ofliquid may be tapped and outiiow spout inserted simultaneously, andwhich provides means for preventing contamination of the liquidremaining in the container during the drawing-off period.

Another purpose of my invention is to provide in connection with theoutflow means a controlled venting and vent ltering means which isoperated synchronously with the outow means.

Another purpose of my invention is to provide outflow and venting meansattachable to the container before it is punctured and which may beallowed to remain in position until the drawing-off of the contents iscompleted.

These and other purposes of my invention will be made more apparent fromthe description thereof which follows, and from the drawing, in which-Figure 1 is a side elevational view of my invention showing itsprincipal features and their position before being attached to theliquid container, the base of the bracket being shown fragmentarily andthe liquid valve and liquid exit piercing means shown in dotted lines.

Figure 9 is a fragmentary bottom plan view of the base bracket clampingmeans illustrated in Figures '7 and 8, and which also embodies theprinciples of the conventional type of clamping means forming a part ofthe device illustrated in Figures 1, 2, and 3.

Figure 10 is a sectional view of the vent piercing and venting meansshown in Figure 7.

Referring to Figures 1, 2, and 3, the bracket for securing the liquidoutflow piercing and vent means to the container comprises a at orconcave surfaced vertical strip member l adapted to t close to thesurface of the container. At the base of the vertical body member Iaffixed to and registering with an opening therein corresponding withits bore is a cylindrical tubular shell or barrel member 2 angularlydisposed thereto and forming the retaining means for the piercing,valve, and vent control mechanism.

Rigidly afiixed to the lower portion of said barrel 2 and vertical bodymember l, or unitary therewith, is an angularly disposed bracket basemember 3, extending oppositely to the barrel member and below the planethereof, as illustrated.

For use on circular containers in vertical position, this base bracketmember 3 andits appendages may be of one of the conventional stylesproviding for positive engagement and holding of the device to theconvex side surface of the container. I have shown one form in Figure 3which comprises a base member extension including identical 'arms 4extending to either side oi the container in Y shape, the base-or footthereof comprising the base bracket member 3, and the arms extendingfrom point 5 toeither side of the container beyond its widest point;`Each of such arms 4 comprises a slidably adjustable arm and clamp 6 andbolt and wing nut 1, as shown in Figures 3, 7, 8, and 9, as means forsecuring the container against the base of the bracket member l.

For use on flat sided containers, or circular containers in horizontalposition, the single extending arm member 6, slidably aflixed to thebracket base 3 with adjustable clamp and bolt 1, as illustrated indetail in Figures '7, 8, and 9, are suicient.

Referring to Figures 1, 2, and 3, the tubular pipe 8 is affixed to thevertical bracket member I and the top surface of the barrel member 2 inthe angle formed by such members, and forms a part of the venting meansin the manner hereinafter described.

Likewise shown in Figures 1, 2, and 3, and amplified in Figures 5 and 6,the tubular barrel 2 is integral with the bracket, and has an inner boresmoothly fitting the outside diameter of the sleeve 9 comprising theliquid exit piercing member and valve mechanism. Referring particularlyto Figures 5 and 6, the top wall of such barrel member 2 is providedwith a'longitudinal end slot I9 to receive and allow horizontal movementof the vent pipe member II, the full extent of such horizontal movementof the vent pipe member I I being shown in Figures-1 and 2, while thebottom wall of the barrel 2 has a similar slot I2 to receive and allowhorizontal movement of the spout I3. Y

Details of the liquid exit piercing and valve mechanism are shown in.Figures 5 and 6, comprising the tubular outer sleeve member 9, tubularbifurcated cutter means I4 with peripheral washer I 4 of resilientmaterial thereon to prevent leakage, said cutter being threaded orotherwise removably secured, and at the outer end of the sleeve member 9the annular ange I5 provides means for securing a peripheral knob I 6.

The bifurcated cutter means I4 shown in Figures 5 and 6 are, forpurposes of illustration, shown in a position involving one-quarter turnfrom that shown in Figures 1, 2, and 3. l

The liquid passage I'I in the cutter means I4 leads to the outflowchamber I8 and its liquid valve, and to the liquid exit throughdepending spout I3. The valve provides means for controlling ow ofliquid through the outflow charnber, the peripheral flange I9 withcentral bore comprising the seat for the valve closure 20 and "passagefor the valve push-rod 2|. Opposing ports or vents 22, 23 in the top andbottom Walls of the sleeve 9 registering with the longitudinal slots IIi, I2 in the barrel member 2 are features of the venting meanshereinafter described in detail.

A wall 24 separates the liquid outflow chamber I8 from the opposite endof the bore of sleeve 9, which wall comprises a central orifice 25 forthe valve push-rod 2|. The push-rod is formed of angular material (suchas square or diamondshaped material) and the orice 25 in the wall 24conforms to the configuration of the push-rod 2| to form a close-fittingbearing therefor. In this way rotary'movement of the rod and leakage areprevented, the advantages of which are hereinafter made apparent.

Means for operating the liquid valve Vincludes the horizontally movableplunger member 26 fitted to the bore of the sleeve member 9, the closure2'I on its outer end providing means for closing the interior from theatmosphere and also for exerting pressure on the push-rod 2I which isafxed to the inner side of said closure. Rotary movement of the plunger2B is prevented by reason of the angular configuration of the push-rod2I and the close-fitting orice in the wall 24.

Reciprocating movement of the plunger member 25 and valve push-rod 2I isfacilitated by the spring 28 intermediate the plunger closure 2'I andwall 24, a washer 29 of resilient material being placed between thespring 28 and the wall 24 to assist in preventing leakage through theorice 25 and is held in position :by the spring 28.

'In lthe bottomwall of the bore of plunger Y215 an orifice or vent 3U isprovided in horizontal alignment with the vent inlet 23 in sleeve member9, while in the top surface thereof another vent 3I is provided inhorizontal alignment with the outlet Vent 22 in the bore of sleeve 9.Each of said vents in the plunger 23 are positioned so they willregister simultaneously with the inlet vent 23 and outlet vent 22 in thesleeve member 9, respectively.

As shown in Figure 5, the plunger member 26 is of such length that whenit is pushed forward in the sleeve 9 to the position where such ventsregister, the forward end of such plunger abuts against the chamber wall24 to prevent further forward movement.

` The purpose of such alignment of the vents just referred to is tocontrol venting connection of the interior of the container with theatmosphere. One of the features of my invention is to prevent bacterialand other contamination of the liquid in the container through themedium of theair that enters the container through the venting means.Contamination is prevented by using a lter in the venting system andthrough which the air must pass after it enters the vent inlet 23 inthesleeve 9 and again before it enters the vent pipe I I.

I have provided such a medium in the form of a cylinder 32 of filteringwool or other suitable material, said cylinder fitting closely the innersurface of the tubular plunger member 26 and preventing air passage tothe container excepting throughl such filtering material. Such cylinder32 of filtering material may be reinforced with a core'33 of Figure 6.

In this form the filter is removable andrenewi able merely by detachingthe valve washer or closure means 20 from the end of the push-rod 2I sothat the plunger 26 may be removed from the sleeve 9 and the filterwithdrawn and replaced through the open end of such plunger.

The peripheral knob I6 is secured to the flange I5 on the sleeve member9, its center bore receiving the outer end of the plunger 26 andproviding means whereby pressure may be exerted on the hole piercingmeans comprised in the sleeve 9 to tap the liquid container.

In the type of my invention illustrated in Figures 1, 2, and 3 the ventpipe II is affixed to the sleeve member 9 in its vent outlet I Il andembodies a right angle turn, the horizontal portion thereof beingslidably arranged in the horizontal portion of the vent pipe 3 securedto the bracket I and barrel 2. Such pipe member 8 thus forms aclose-fitting sleeve for the vent pipe II movement thereof. Packingaround the vent pipe Il at the entrance to the pipe 8 prevents pressureor air leakage.

Figure 1 shows the position of the vent pipe I I in the horizontalportion of tube 8 before the piercing operation, such operation carryingit into the slot I0 in the barrel member 2 and into the sleeve formed bythe tube member 8, as shown in Figure 2. The slot I2 in the lower sideof the barrel 2 allows for similar operation of the depending spoutmeans I3, as also shown in Figures 1 and 2.

The upper end of the vertical portion of the tube member 8 forms thesleeve for the vent pipe member 34, the lower end of which is slidablyarranged therein, to allow for vertical telescopic movement. Packingaround the vent pipe at the entrance to said tube also prevents leakageof and allows for horizontal telescopicv pressure or air at that pointfrom within the venting means.

In the type of my device illustrated in Figures 1, 2, and 3 the top endof the vent pipe 34 is bent at a right angle to the lower portion andcomprises a connecting member which acts as clamping means for holdingthe top portion of the device on the container and means for piercingand venting the top portion of the container.

The vent pipe 34 is connected with the vent chamber 35, as shown inFigure 4, with tubular bifurcated piercing and venting means 36 formingthe entrance thereto. The convex knob -31 on the top surface of suchmember facilitates the application'of pressure to the piercing means 39and handle means to pull it from the position shown in Figures 2 and 3to that shown in Figure 1, while the washer 38 of resilient materialaround the outer periphery of the cutter member 36 insures againstleakage of internal pressure or air when compressed against the topsurface of the container in the manner shown in Figure 3.

Figures 7 and 8 illustrate a variation in the form of my invention tomake it specially adaptable for use on the ends of containersy lying inhorizontal position.

The container piercing means, outfiow, valve, and venting controlmechanism are identical with that in FiguresI and 6, with the adjustableclamping means 6, I hereinbefore described for attaching the base of thedevice to the container.

The vertical portion of the bracket member I is of fiat materialarranged with a vertical grooved slot of the conventional type toreceive an extension of said bracket comprising a at strip of material39 slidably arranged in such grooved slot to allow vertical movementthereof so that its length may be adjusted to containers of varioussizes as well as to provide for its extension as a means of removal fromthe container. At the top of the sliding portion 39 the hook or fingermember 40 is provided to clamp over the edge of the container.

Pins 4I, 42 in the lower portion of the vertical bracket member I and inthe upper portion of the vertically movable extension bracket portion 39provide means for securing the spring 43 by end hooks 44, 45 to saidpins, the spring means drawing the bracket extension 39 downwardly inits grooved slot to hold the device on the container in the manner.illustrated in Figure 8. Telescoping tubular sleeve members 46, 41fitted over the spring 43 may be provided in the manner shown.

In this latter type of my device I have also provided a vent piercingand vent chamber means which allows for a horizontal piercing operationin order that "the end of the container may be pierced. The cylindricaland tubular barrel member 48 isl affixed on and at right angles to thebracket extension member 39, its bore registering with an orifice in theextension member and provides sleeve means for the vent piercing means.

The vent piercing member comprises the knob 49 fitted on the outer endof the tubular valve chamber member 58, with the tubular bifurcatedpiercing cutting means 5I aixed to the opposite end. A vent 52 isprovided in the side wall of said chamber member 5U, said vent being soplaced that when the cutter has been inserted into the container thevent registers with a corresponding slot in the barrel member 48, and acommunicating vent pipe 54 corresponding with the venting means II, 8,34 shown in Figure 1,

connects the vent chamber 50 with the vent outlet 22 of the sleevemember 9 comprised in the vent controlling mechanism.

As shown in Figures 7 and 8, I have provided for the vent pipe 54 to beof flexible material, such as rubber hose, of such length that there iscontinuous connection notwithstanding varying positions of the partsresulting from the horizontal movement of the vent and valve controllingmeans.

Explaining the operation of my device illustrated in Figures l to 6incl., with its various parts in the position shown in Figure 1, themetal container to be tapped is inserted in upright Yposition betweenthe top vent piercing means 35 and the base member 3 of the bracket, andflush against the vertical bracket member I.

The base of the container is then secured in position by adjustment andbolting of the slidable clamps 6 and wing bolts l, while downwardpressure on the top vent pipe 34 and its appended vent piercing means 36will force the bifurcated cutter through the top of the container,securing the container in position at that point and at the same timecutting the vent and connecting the vent chamber 35 and vent pipe 34with the top interior of the container.

Pressure on the knob I6, forcing the sleeve member 9 from its positionshown in Figure 1 to that shown in Figures 2 and 3 causes the bifurcatedcutter I4 to pierce the container wall near its bottom, providing theliquid outflow means by which the contents may then be drawn through thetubular cutter I4, valve chamber I8, and spout I3.

Outflow of the liquid is prevented, however, when the valve is in thenormally closed position shown in Figure 6. Only when pressure on theplunger 28 at its end 2I unseats the valve closure 28, as shown inFigure 5, is it possible for i the liquid to escape from the container.

It will also be noted that when the valve closure 20 is in the closedposition shown in Figure 6 the vents 38, 3| in the plunger are not inregistry with the inlet and outlet vents 22, 23 in the sleeve 9. Thisprevents the exit of pressure from the container or ingress of air toit, and is especially valuable in preventing flatness in liquids such asbeer or other types of carbonated beverages. In the same manner ingressof air to the contents during the time the liquid `valve is closed isprevented and contamination avoided. The filter means 32, 33 alsoremoves contaminating matter from air that is admitted through the ventinlet 23 and venting means to the top of the container, and is a furtherprotection against spoilage and contamination.

When the valve is opened by pressure on the plunger 26, the vents in theplunger and sleeve member 9 register and open the venting passage fromthe vent inlet 23 through the plunger 25 and lter 32, 33, vent outlet3l, 22, and through theiconnectingvent means II, 8, 34 and vent chamber35 to the top of the container, while the liquid flows through thepassage Il in the tubular hole piercing means I4, valve chamber I8, andexit spout I3. The release of the plunger 2B seats the valve closure 20,stopping the flow of liquid, and cuts oi the venting passage.

The style of my device illustrated in Figures 'l' and 8 is operated in asimilar manner, the container being placed on its side and the endinserted between the bracket base member 3 and the top bracket clamp 40.By means of the spring 43, the bracket portions I, 39 are pulled held atthe upper surface, while the slide clamp extension member 6 is fittedalong the lower side with the clamp securing the opposite end ofthecontainer andgupon fastening of the wing bolt 7 or such `other meansthat may be provided, the lower end of the container is held against thebase of the vertical bracket member l Pressure on the knob 49 forces thebifurcated cutter means through the container to the position shown inFigure 8, and provides venting passage from the interior of thecontainer through the vent chamber 52 and vent pipe conm nection 5t tothe vent outlet 22 in sleeve 9.

The liquid outflow means at the base of the bracket is then provided bypressure on the knob IG controlling the piercing member I4, and thedevice is in position for operation as hereinbefore described. Y

When the container is empty the device is removed by releasing the bolt'l and base clamp 6, withdrawing the piercing means I4 by an outwardpull on the knob IE. In the form of my device illustrated in Figure 8the vent piercing means 5I must then be withdrawn from the container byan outward pull on its knob 49 and the top clamp 40 pulled away from thecontainer, while in the form shown in Figure 3 withdrawal of the ventpiercing means 36 by upward pull on knob 3l also releases the top of thecontainer. The device is then ready for reuse upon another container.
